FAQ
What information do you need to start fixing the mern bug or react bug?
To resolve the issue quickly, I need a brief description of the react bug, any error messages (screenshots or console logs), and access to the source code (GitHub repository or a Zip file). If the bug is on the live site, the website URL will be helpful.
Can you fix the mern bugs or react bug via TeamViewer or AnyDesk?
Yes, if the issue is environment-specific or if you prefer not to share the source code, I can assist you to solve react bug or mern bug via remote desktop tools like AnyDesk, TeamViewer, or Zoom. Please message me to schedule a time.
How long does it take to fix a MERN stack error?
Most common bugs (UI glitches, React Bug or Error, CORS issues, or API errors) are usually resolved within 2–6 hours. Complex logical errors or deployment issues may take up to 24 hours. I always prioritise urgent fixes.
Do you offer long-term support for my mern application?
Absolutely! I am available for long-term maintenance, regular updates, and ongoing bug fixing for your react or MERN stack applications. We can discuss a custom monthly plan if you need continuous support.
